Converting bytes to megabytes

Question

I\'ve seen three ways of doing conversion from bytes to megabytes:

1. megabytes=bytes/1000000
2. megabytes=bytes/1024/1024
3. megabytes=bytes/1024/100

Answer 1

Traditionally by megabyte we mean your second option -- 1 megabyte = 2²⁰ bytes. But it is not correct actually because mega means 1 000 000. There is a new standard name for 2²⁰ bytes, it is mebibyte (http://en.wikipedia.org/wiki/Mebibyte) and it gathers popularity.
